SIRENA

One of the main applications of nanotechnology is the manufacturing of polymer nanocomposites, reinforced polymers with low quantities of nanosized ingredients dispersed into a thermoplastic or thermoset matrix. The use of nanoparticles (NPs) in composites production offers enormous advantages over traditional macro- or microsized fillers and applications across a wide range of industrial sectors are currently on the market.

Industry must evaluate and, if feasible, quantify the risk of nanomaterials (NMs) embedded into composite matrixes release to the environment throughout the life cycle as an integral part of its design processes. This information should be made available to the relevant regulatory authorities and consumers.

The main goal of SIRENA is to demonstrate and validate a methodology to simulate the unintended release of NMs from consumer products by replicating different life cycle scenarios to be adopted by a wide number of industrial sectors in order to get the necessary information for exposure assessment.

» NANOSTRUC 2018 is now open for abstract submission!

NANOSTRUC 2018 taking place in Berlin (Germany) on the 23-24th May 2018 is now open for abstract submission. All accepted Papers will be published in the IOP Conference Series: Materials Science and Engineering (MSE) and full papers solicited to a number of ISI Journals associated to NANOSTRUC 2018 Conference.
Like in previous conferences, the purpose of the International Conference on Structural Nano Composites (NANOSTRUC 2018) is to promote activities in various areas of materials and structures by providing a forum for exchange of ideas, presentation of technical achievements and discussion of future directions.
NANOSTRUC brings together an international community of experts to discuss the state-of-the-art, new research results, perspectives of future developments, and innovative applications relevant to structural materials, engineering structures, nanocomposites, modelling and simulations, and their related application areas. For additional information, please contact James Njuguna (j.njuguna@rgu.ac.uk) or visit link.

» New articles published!

Two new articles have been published describing the approaches implemented in the framework of SIRENA and efforts in the standardization of the evaluation of exposure associated to the life cycle of polymer nanocomposites. The articles describe the main outcomes of the team from the RGU in collaboration with VITO; on the one hand the experiments assessing the particle release during drilling processes on the epoxy resin containing Carbon Nanotubes and Carbon Nanofibres respectively are described and, on the other hand, the evaluation of the “filler effect” on emissions associated to the drilling of polyester nanocomposites, ie, how the presence or absence of nanosilica and/or nanoalumina modify such emissions. Please, go the Dissemination Materials section if you want to access the complete references.

» ISO/TS 12025:2012

An article by Stintz and Göhler dated 2015, on the standardization needs in particle technology, refers that published studies regarding nano-object release into air lack from three key issues: a consistent terminology, standardized metrological procedures and the method for data evaluation. Thus, a quantitative comparison between the different studies is often difficult or impossible, if necessary parameters are missing. To fill this gap, ISO/TC 229/WG 2/PG 10 has developed the technical specification (TS) ISO/TS 12025:2012, which is a general framework for determining airborne release of nano-objects from nanostructured powders by means of aerosol analysis. The TS provides information on the methodology for nano-object release quantification that covers beside necessary measurands and process parameters also the presentation of measurement results by specific release numbers. ISO/TS 12025:2012 supports also standardization regarding nano-object release testing on nanocomposites, e.g. abrasion procedures lead to powdered wear prior a possible aerosolization. To date, no additional technical specifications have been published.
